PHP rsort
| Back to forum moderator (2008-08-02)  |
Definition and Usage
The rsort() function sorts an array by the values in reverse order. This function assigns new keys for the elements in the array. Existing keys will be removed. This function returns TRUE on success, or FALSE on failure.
Syntax
rsort(array,sorttype)
array : Required. Specifies the array to sort
sorttype : Optional. Specifies how to sort the array values. Possible values:
* SORT_REGULAR - Default. Treat values as they are (don't change types)
* SORT_NUMERIC - Treat values numerically
* SORT_STRING - Treat values as strings
* SORT_LOCALE_STRING - Treat values as strings, based on local settings
<?php
$my_array = array("a" => "Hamburger", "b" => "Cheese", "c" => "Jam");
rsort($my_array);
print_r($my_array);
?>The output of the code above will be:
Array
(
[0] => Jam
[1] => Hamburger
[2] => Cheese
